Environment and sustainable development are very current topics in today's society, both national and international. The government's bill 2004/05:150 ”Swedish environment objectives - a common commission” contains several environmental quality objectives, that in turn is divided up in smaller secondary objectives. One of the secondary objectives says: “Latest year 2010 shall at least 35% of the food waste from households, restaurants, largescale kitchens and shops be recycled through biological treatment. The objective intends source separated food wastes to composting at home as central treatment”. The aim with the project is to investigate which initiatives are required in order for Halmstads municipality to achieve the secondary objective concerning 35% recycling of food wastes. During the sorting of household combustible waste in Halmstads municipality today, there is no sorting of food waste. This means that only food waste from restaurants and large-scale kitchens are collected for further biological treatment. Systems for handling waste are complex and many factors play a part when choosing the most favourable collection system for each municipality. An inventory shows that recycling of 5500 tons of food waste is required in order to fulfil the secondary objective. There are several different solutions to collect this amount. My proposal is to use a two vessel system in households, restaurants and large-scale kitchens. This means that the waste is separated into two different containers. The waste will be sorted into sealed plastic vessels of which one is for biological waste, and the other for combustible. In order to keep the two vessels a part, two different colours could be used. For example, a brown vessel for biological waste and a green one for combustible. The households should also be able to use home composting as a complement. At restaurants and large-scale kitchens there should be the possibility to an alternative collection through a garbage disposal unit with a container. When the vessels are emptied, the combustible waste goes to incineration and the food waste is taken to a biogas facility.
